If you are running differential signals between to racks through a
shielded cable, what should you do with the cable drains?
Hard wire both-ends to the chassis?
Hard wire one end and let the other float?
Float both ends?
Connect through a series resistor, or series cap, or series cap and
resistor in parallel?
Is there a rule of thumb or formula based on something to help you
determine how to connect the shielding?
I have seen it done several different ways but never have been real sure
which way is correct.

Thanks,
Stacy
